NOT SNAKE OIL! I REPEAT....NOT!! I used on my GT as per the instructions and has been awesome ever since! Like everyone says about the product, you have to do exactly what the instructions say and youll be good to go!
what "kind" of Head gasket ??? Are you using "steel shim" gasket? Most manufactures tell you in the instructions, in BIG letters, to INSTALL DRY. In the old days, we used to use sealer, Usually permarex. but not for the last 25-30 years.

Do a google search on blue devil, its an additive you put into the coolant system which seals the leak. Lots of positive reviews on it.

On the steel shim gasket, I always sprayed mine with a thin coat of aluminum paint. On the composition gasket I still use permatex aviation form a gasket. I bought a pint of it back in 1976 and I still have half of it left. You use it in very thin coats. But technology changes, blue devil is the new Bars leak I have always used on my engines... Before Bars leak, we used sodium silicate or water glass as it was known as. Actually. water glass was very good at sealing blocks and gaskets, but it was time consuming, as you needed to let it air dry after running it in the engine till it got up to temp. That took a day or two to do. I had a friend that would hook up a hair dryer (old style, not a blow dryer) to speed up the cure. You can always try new things, and see if it works or not, if not, correct it and try again with proven products.
I have always used a coat of good old Aviation gasket sealer on both sides of head gaskets of any type. Even the Fel-Pro ones. I'll let you know if I lose one. I've seen guys use furnace paint. It's tough to screw up a sealer if the block and heads are flat.
I've used blue devil on a 95 grand prix with a 3100 and it worked.great. drove the car.another 2500 miles then sold the car the kid drove the hell out of that thing and it still held up. He ended up wrapping it around a tree one night a good year and a half after I sold it to him. I asked if he ever had any issues with the motor after I sold it and he said nope it ran.like a champ

Use any gasket sealant with Fel-Pro's head gaskets, Printoseal or not, the sealant can cause problems select. Fel-Pro instructions said install dry, they mean it.

Ill totally agree with that. On ONE engine for my Tbird I raced, I wanted to be sure the pan seals and gaskets didnt leak and we put sealant on them. Within an hour of startup, the gaskets were sliding out of the joint. Tightening the bolts only made it worse. Had to pull the pan back off, clean the surfaces and put new gaskets on with no sealant and no more leaks. Since head gaskets are 'hard', i wouldnt see that as a problem though. I just learned if it dont SAY to use a sealant...DONT.

Maybe, but untill I see it, no. And I'm a long way from young.
